Group 1 Group 15 Three group 1 atoms loses 1 e, forming 1 ions. One group 15 atom gains 3 e, forming a 3 ion. The ions attract, forming X 3Y, where X represents a group 1 atom and Y represents a group 15 atom. Section 7.2 Assessment page 217 12. Explain
To illustrate, an atom of an alkali metal (group 1) loses one electron and forms a ion with a 1+ charge; an alkaline earth metal (group 2) loses two electrons and forms a ion with a 2+ charge, and so on. For example, a neutral calcium atom, with 20 protons
